I think the next Nulite will be them proclaiming the great tribulation has begun, so expect imminent persecution.
In reality they will just replace the overused "last days' with "great tribulation" to get people active and productive.
I agree. It's a win-win for them:
1. The Great Tribulation is of an indeterminate length. Therefore, they could milk this for DECADES.
2. They don't have show any actual proof. Something along the lines of: "Only Jehovah's people were able discern that Jesus began ruling in 1914, even when world events made it obvious. As before, Satan has 'blinded the minds of the unbelievers'. The world does not yet recognize that its governments have already turned on Babylon the Great-- stripped her of the power and its wealth she once enjoyed. Her waters are indeed 'drying up'. Through their rhetoric, the nations declare 'peace and security', while the reality is anything but. Therefore it is with great confidence we can declare that we, as Jehovah's named people, are in fact living in the time period foretold in Revelation as the 'Great Tribulation!'"
3. Such a grand revelation that "the Great Tribulation has in fact begun" would send the vast majority of J-dubs into a frothing-at-the-mouth frenzy. Conventions and assemblies for years following the announcement would be re-framed around the GT having already begun, and therefore we are that much closer to the Big A.
There would be zero downside for them.
